TANK FOR WlNDli/IILLS.

SPECIFICATION forming part of Letters Patent No. 298,793, dated May 20,1884. Application filed March 10, 1884. No model.)

To wZZ whom, it may concern.-

Be it known that I, HARRY R. STEVENS, a citizen of the United States,residing at Los Angeles', in the county of Los Angeles and State ofCalifornia, have invented a new and useful Tank for Windmills, of whichthe following is a specification, reference being had to theaccompanying drawings.

I have found by experience in the use of water-tanks in connection withwindmills throughout the southern and southwestern sections of theUnited States that the wooden tanks constructed of a woodenbottom,wooden staves, and iron hoops, and those constructed wholly ofsheet metal, are not sufficiently dura ble to be practicable, owing tothe fact that the wooden staves, when subjected to the action of the sunin the sections of country referred to, soon become shrunken and causethe tank to leak and fall to pieces, and the bend connecting the bodyand the bottom in the tanks constructed wholly of sheet metal is rapidlyworn out and broken by the eX- pansion and contraction of the metal atthis point.

To obviate these defects is the object of my invention; and to theseends it consists in the construction and novel arrangement of parts, aswill be hereinafter fully described, and particularly pointed out in theclaim.

Figure l is a vertical sectional View of a water-tank embodying theimprovements of my invention. Fig. 2 is a view of the encircling hoop,and Fig. 3 is a view of the strengthen1ng-w1re.

Referring by letter to the accompanying drawings, a designates thebottom of the tank, which is made of redwood or other suitable wood; andb is the body, made of galvanized sheet-iron, constructed of two or morewidths of material riveted together at their lapped edges. The loweredge of the blank of which the body is formed is first bent over thestrengthening-wire c, and the bent portion eX- tended up along the innerface of the blank.

The vertical seam t is then formed by lapping the end edges of theunited Widths and securing them together by rivets, and th; woodenbottom driven to place over the bea d, formed at the bottom of the body.The err circling hoop e is then driven to place directly A tank thusconstructed is simple, cheap,

and durable, and will not be injuriously affected by the expansion andcontraction of the metal.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

The herein-described water-tank, consisting of the body of galvanizedsheet-iron bent inwardly and upwardly over a strengtheningwire near itslower edge, the wooden bottom fitting tightly in place over the beadformed at the lower edge of the body of the tank, the encircling hoopfitting tightly over the body directly opposite the edge of the woodenbottom, the metal flange bent downwardly and inwardly over the woodenbottom, and the calking in' the space between the body-wall and thevertical portion of the upwardly-bent flange, substantially asspecified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of witnesses.
